Does this mean I can spread the regions over a cluster of machines,
not a single SMP box? So e.g. I could run 4 regions on a 8-GByte
dual- or quad-core box, and four on another box, with dedicated GBit
Ethernet links by crossover cable, or by bundling the individual
Ethernet interfaces? 

I presume the systems speak XML over wire? Does InfiniBand help?

So a dual-core Opteron box should be able to handle 4 regions at ~100% CPU load?

Thanks for the information.
